Installing additional Perl modules to help with module creation

In the documentation for creating/writing modules, it says that cPanel does not use system-wide installed modules, and that they should be placed here:

Code:

/usr/local/cpanel/perl

So I installed XML::SimpleObject and copied the directory from here:

Code:

/usr/lib/perl5/site_perl/5.8.8/XML

To here:

Code:

/usr/local/cpanel/perl

When I do a perl -w on the file, no errors show up, however, the module that used to work in cPanel (using CP tags since I'm using API2 format) no longer works, unless I remove the use call for XML::SimpleObject.

How exactly should you add additional Perl modules to cPanel so they can be used?
